- iOS 11.0+
- Mac Catalyst 13.0+
The text view where the drag activity was started.
The current drag request.
An array of drag items that represent the items to drag.
You implement this method when you need to provide custom drag items. The drag request gives you the text range of the text that is included in the drag activity. It also gives you the default drag items, which you can add to or change. If you return an empty array, the drag operation does not happen.
